execvp replaces the current process with the new one, so your program "stops executing" as soon as you call execvp. You need to call fork() first to make a new process.

I believe your only choice is to change the typedef or create a new typedef or not use it:
typedef const int *ptr;
ptr p;
Okay, so you've managed to create a loop, but it's not much use because it insists on reading exactly 5 characters from the file. What you want is a loop that continues until you read the end of the...
Plenty of languages other than C support arbitrary precision arithmetic natively, and project euler doesn't require the use of C. If you need/want to use C and don't have C99 long long support (you...
Great, where's what you've got so far?
No.
Looks like homework. Show an attempt first. You might use fgetc which reads characters or fgets which reads lines (provided the buffer is big...
You are correct that it's casting it to a pointer to struct sockaddr, but C does not have "pass by reference". You are passing a pointer to sin.
I can't think of any easy (or practically feasible way). This is why most programs that allow third party plugins invent their own domain specific language and just parse that themselves, instead of...
You've presumably not worked with gcc then? It will show this with -W or -Wextra.
This is undefined behaviour, as is the original poster's code. You may only use a character pointer. If you have the ISO/IEC 9899:1999 standard handy, see section 6.3.2.3 paragraph 7.

No, malloc() does not initialise the space it allocates, as already said by Salem.
Only if you count variations on the above, such as making the first element of the array the length.
When you use int a[] in the parameter list of a function declaration it's equivalent to int *a;...
Yes, there's no standard way, as Salem already said.

Actually 48 :p

I said %f was float. A double is not the same as a float.
In scanf, use %lf for a double, and %f for a float.
In printf, use %f for both. It's inconsistent, but there's a reason for it.
You are trying to pass a float (%f) into an int (input), you don't want to do this.
Other than that, at first glance, your array filling function appears to be reasonable. The code calling...
getline() is not a standard C function, fgets() is, and is the preferred alternative to gets(). The problem with gets() has nothing to do with "flushing the buffer", and is wholly to do with not...
memset just sets bytes of memory to a specifieed value, it has nothing to do with memory allocation.
If you are using malloc(), the only thing you want to use to free it, is free().
By the way,...
I'm guessing m/c is microcontroller. Look at /proc/cpuinfo to see if there's a processor difference?
It's allowed in C99.
If your array type is int, then memset over the entire thing should be safe:
memset(array, 123, sizeof(array));
If it's not an int, then individual assignment will be required, as you...
You don't really need the convoluted arithmetic:
/* prints "3" */
printf("%.0f", 3.14159265);
/* prints "4" */
printf("%.0f", 3.6);
/* prints "3.14" */
printf("%.2f", 3.14159265358979);

Well for a start trunc takes a double and returns a double, and you're playing with ints.
Secondly, i is an int (integer), so it can't store a value of 5.156546 (not an integer).
Please show a minimal test case that we can see your code and run it.
